摘 要:以高产、抗病、高淀粉为育种目标,选用俄罗斯引进的马铃薯品系гибрид82作母本、俄罗斯品种Журавинка作父本,通过有性杂交,系统选育法育出高产、抗病、高淀粉品种垦薯2号。为中晚熟淀粉加工型品种,干物质含量25.71%~29.51%,淀粉含量19.71%~23.51%,VC含量49.3mg·kg^(-1),还原糖含量0.07%。平均产量为34338kg·hm^(-2),田间对晚疫病的抗性强于对照克新12号,高抗PVX,抗PVY,适宜黑龙江省各积温带种植。Taking high yield,good resistance to disease and high starch content as breeding targets,this study selected гибрид82 introduced from Russia as female parent and a Russian variety Журавинка as male parent;and developed ‘Kenshu No.2' with high yield,good resistance to disease and high starch content by system selection method.‘Kenshu No.2' is of mid-late maturity and starch processing type. Its dry matter content is 25.71%-29.51%,starch content is 19.71%- 23.51%,VC content is 49.3 mg · kg^(-1) and reducing sugar content is 0.07%. Its average yield is 34 338 kg·hm^(-2). It has high yield and high starch content. Its field resistance to late blight is stronger than that of the contrast ‘Kexin No.12'. It is highly resistant to PVX and resistant to PVY. It is suitable for planting in Heilongjiang Province.
